Scores are a bit scattered, possibly reflecting memory configuration and speed? Gen 2 seems a hair faster...

What the heck are you talking about????

AMD's next-generation Ryzen chips, due to hit the shelves in a few months, should have excellent performance-per-watt, possibly significantly better than Intel's offerings. Watch the first 4 or five minutes of this video: https://www.youtube.com/watch?v=g39dpcdzTvk These chips will almost certainly ...

What am I missing? I don't see any way to force the black king off the c-file w/o dropping the d3 pawn (which appears to actually loose!)

Larry, anyone.
Halving the cpu resources should cost the typical engine somewhere around 20(?) elo? Yet MPV =2 kills ~100 points. Why is the MPV performance hit so high? (A simple question with - I suspect - a complex answer! )

Here are some benchmarks. As suggested, be sure to get a card capable of the running the fp-16 back end, as seen in the config notes. "--backend=cudnn-fp16"

I'm not 100% sure this is happening, but it seems that setting MultiPV to N causes the engine to search all N first moves to a more or less equal depth. This short-circuits the engine's finely tuned pruning parameters and theoretically weakens the engine slightly. But the engine is also significantl...
